IMPROVEMENT In nArBLoerINe nnenrnss.

Be it known that I, JULIUS SnELDon, 'of the city, county, and l State of New' York, have invented new end.-l

usefulA Improvements in Hat-Blocking Machines, and that thefollowing is a full and clear description thereof,

reference being had to tho annexed drawings, of which-#- Figure 1 is a-vertical section of the machine in such n positionne it requires to.. bebeforeth'e operution'of blocking a hat-body commences.

o v Figure 2 is also u vertical section of the machine, showing -the various parts infthe'position in-which they will be when thelist-.body is blocked or stretched 'to the shape required. Figure 3 is nplan view of' the maehinein the position shown ing. 2, showing only two of theclumps. Figure .4 represents the'lower side of the plate. l

v My improvements consist in arranging the various parts of the 'hat-blocking Amechine .patented to Joseph De Lamai-,so os to make them adjustable in regard to size nnd depth so that every si'ze and depth Aofliat can he made/on euch muehine, and also in the apparatusl for giving the proper pressure to the clamps, which perform.

the stretching ofthe brim` of the hat, and in the mechanism for opening and c losing said clamps.

.Referring to the drawings, a is asqu-are table, inv the centre vof which there is a hollow' vertical stem, I,

through the centre of which 'runs a rod, c, whiclrbearsat its upperl extremity a round hub, d, to which. are hinged u number of arms,` e. Eaclrof these firms is hinged Ato the upper end of u vertice-l bul-, f, whichhes v stationary but adjustable fuleruni et g, below the plate L, to which the clamps-z' are jointed. These bars-f perform the stretching of the crown by expanding, es shown in' the drawings, the, hot-body being held at .the .place where the band of the hat requires to be by a. ring, 7c, which determines thefsize of the hut. Thev fulcrum g, on which the barsf turn, consists ofc-pin inserted in the slotted'pieceslond these pieces Zslide in.guides,m,s.nd can be shifted in und out', 'to Asuit' the size of the lint"required, by af cone, it, which turns von a; screw out on the hollow stem b. In order to adjust these bursfto the depth of thelist the lower partofthe'se bars iis-provided with notches, g", about (al) one-fourth of an inch distant from each other, serving as seats'for the fulcrum pinsl g, so that When the bars orc all placed' so that the upper notches engageV the fulc'ru'm pins the lowestlhnt 'con be m'adeon the inneliine, and when they are placed so that the lowest notchesengageth' fulcu'mpin's the tallest hat can be made. There is an elastic ring, o, placed all round these barsf, right'belowthe plate tan'd opposite the fulerum, for the pt irposcl of keeping-'the notches in gear with'their fulcr'umpins. The ring cLwhieh breaksl the bland, is provide'dm'itli an India-rubber oushiomj, all 'round its periphery, wide enough to'press upon the clamps z', when ring 7c is brought down upon -the hat-body, and to keep up this pressure while the clempsare being raised toa horizontal position. The outer partsfz'l of the clernps z' arevprovided with vshort arms, i, by

which-all the clamps'can bevclosed simultaneously by means of a'ring, @which receives an upwardmotion by levers,'], comes in contact with the 4arms iz, closes theolnmps, and 'holds Atchem so until the ring 7c is brought down upon them-. In order to open all the clumps simultaneously when the hat-body is to be removed the arms of the .outer jaws of the clamps moy .be provided with c'ount'erLw' eights,g,l or the outer jaw 'maybe thrown 'out byxaspring attached tothe innerjuw. Y l o y vThe operation of the machine isos follows: The'hutfbody is placed voverthe machin-e; the ringp is raised, which closes the clamps; then the ring 7c is brought down upon the hatbody, v und lits cushion gives pressure to the clamps. Now the clamps can be raised, thereby bringing out the brim flipt; and' at last -thecrown celibe stretched. ,A

I am aware of the application of'Joseph De namur, led'November v1866, und herebydscleim all the features of his invention; hut whot I claim as new, and as improvements-upon the 'invention above referred to,

and desire to secure by Letters Patent, is o p '1. The barsf, provided'withnotches gA for `the purpose ofadjusting said b ars'to all depths of hats, substan,

tinlly as described.

- 2. I -cloim the slides l, provided at one end with pins g,'wn1cha-c't asthe fulcro of bursf, and/ having 4their I`inner ends so :arranged with the cone n as to be adjustable,"substantially as described. -I l 3. '.lhe ring 7c, provided with a surrounding elastic cushion to adopt it` to the two functions of breaking the band and 'giving the pressure to the clumps, substantially as described.

` 4. I claim the ring 15, disconnected from butarranged to operate the clumps z', substantially as and for the purpose specified.
